The present invention relates to improvements in loading hooks such as are used with a steam log loading or decking machine where a wire cable and a crotch lineare associated with thehoo-k or hooks in loading logs on cars. a

One of the important objects of the-presein-t invention-is to provide a log loading hook wherein the log engaging tooth is de- 'ta-cha'bly. secured inthe outer end of the foot portion ofthe hook so'that the same may be readily and easily removed whenever it becomes necessary to resharpen or replace the same.

A still further object is to provide a log loading hook wherein the tooth is bifur: cated to provide a pair of prongs. The hooks being further constructed of such material as to render the same strong and durable.

()ther objects and advantages of thein- 'vention will become apparent as the nature of the invention will be better understood.

In the accompanying drawing forming a i part of this application and in which like numerals designate like the several views:

Figure 1 is a side elevation of the log loading hook embodying my invention.

Figure 2 is an edge elevation thereof.

Figure 3 is a detail perspective view of the tooth.

Figure 4 is a transverse section through the lower portion of the shank of the hook taken approximately on line 44 of Figure 1, and

Figure 5 is a similar section taken approximately on line 55 of Figure 1.

In the drawing wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates generally my improved log loading hook, the same comprising the shank portion 2 at the upper end of which is formed the eye 3 whereby the hook may be attached to a cable or rope in the manner well known in the art.

The shank portion 2 of the hook increases gradually in thickness and in width toward the lower portion thereof as clearly illustrated in the drawing, and a substantially right angularly disposed foot 4; is formed on the lower end of the shank. This foot gradually decreases in thickness toward its outer end. By constructing a hook in a manner as above described, the same will parts throughout give the greatest strength Wherever it is needed and yet be as light as possible. An

apertured ear 5 extends from the bottom of the inner portion of the foot 4 of the hook, and as this particular detail forms'no important part of the present invention and isfur-thermore well known inthe art a further description thereof is thought unnecessary. l

Theouter free end of the :foot 4 -is slightly enlarged as indicated 'at 6 and is provided with a vertical opening which is substantially rectangular in cross section and is indicated by the numeral The detachable tooth forming a part of the present invention is shown generally at 8 and the same is provided with a depending tongue on the bottom face thereof, said tongue being also substantially rectangular within the opening 7 formed in theenlarged outer end 6 of the foot 4 so that'the bottom face of the tooth 8 will rest on the upper face of the enlarged portion 6.

For the purpose of locking the tooth 8 against accidental displacement from the outer end portion of the foot of the hook, I provide the cotter pin 10 to extend transversely through registering openings provided therefor i'n'the opposed sides of the enlarged portion 6 of said foot 4 and also through a suitable opening 11 formed in the depending tongue 9 of the tooth 8. The free ends of the cotter pin 10 are adapted to be disposed outwardly in opposite directions for engagement with one side face of the enlarged portion 6, while the head of the cotter pin engages the opposite face. This construction is clearly shown in Figure 2 of the drawing.

The tooth 8 has its outer face beveled as indicated at 12, and is furthermore bifurwhich is adapted -l11 cross section and being adapted to fit cated to provide a pair of prongs 13 and 14 respectively. The inner opposed faces of these prongs are also beveled so that the upper ends of the prongs are'pointed. The tooth 8 is preferably constructed of a high quality tool steel so that the same will withstand breakage as well as preventing the prongs becoming dull for a relatively long period. The provision of a pair of prongs insures greater strength and more efficient gripping of the logs.

The simplicity in which my improved log loading hook is constructed enables the tooth to be readily and-easily detached whenever it becomes necessary to resharpen the prongs or for the purpose of replacing an old tooth with a new one, and furthermore the provision of the securing means for the detachable tooth will save considerable time and labor in inserting or removing the same.

While I have shown the preferred embodiment of my invention it is to be under stood that minor changes in the size, shape, and arrangen'ient of to without departing from the spirit of the invention and the scope of the appended claim.

Having thus described the invention,

vwhat I claim as new and desire to secure by Letters Patent 1s:-

- A log loading comprising a shank portionhaving an eye 'torined at one end thereof, a right angularly parts may be resorted hook of the class described disposed foot formed at the opposite end thereof, the outer free end of said foot being enlarged and provided with a vertical opening, the bore of which is substantially rectangular, a tooth, a substantially rectangular tongue depending fro-1n the bottom face of the tooth and adapted to be disposed within said rectangular opening, whereby the bottom face of the tooth will rest on the upper face of the enlarged portionof the foot, a pin extending transversely through the enlarged outer-end portion of the foot and through said tongue for detachablysecuring the tooth in said opening, he outer face of the tooth being beveled, said tooth being bifurcated to provide a pair of prongs, the inner opposed faces thereof being beveled to provide sharpened upper points.

In witness whereof I afiix my signature.
